ESD Precautionary Check List
The following table provides an Electrostatic Discharge Precautionary Check List for
handling ESD sensitive parts in the SAN256N director.
As you review this check list, keep in mind that all steps suggested will help minimize
ESD damage to the equipment because of its sensitivity to any type of static discharge.
The chronological order of checks suggested by this list might not always have to be
performed in the order suggested. Modify this list as applicable.
Table 1. ESD Precautionary Check List
General ESD Precautions and Controls Yes No Not Applicable
Are grounding connections (grounding wrist strap, ground
wires on cords) checked for electrical continuity?
Are the cabinet AC power cords plugged into a properly
grounded AC outlet in order for the chassis to be grounded?
Does conductive flooring have a resistance of less than
100K ohms from any point on the tile to earth ground?
Are surface resistivity tests performed and results recorded
on conductive floors?
Are ESD wrist straps worn by personnel when working with
ESDS PCBs?
Are personnel handling ESDS components receiving ESD
training? Are ESD training records maintained?
